Application led October 28, 1915. Serial No. 58,470.

vcounty of Morrow and State of Ohio, have invented certain new and useful Improvements in Reinforced-Concrete Pipes, of which the following is a specification, ref,- erence being had therein to the accompanying drawing.

This invention relates to -reinforced concrete pipes and has for its principal object the production of a simple and eliicient reinforcement which is positioned within the pipe at the time of its construction, so that upon the completion of the pipe 1t will be greatly reinforced and prevented from breaking or cracking when in use.

Another object of this invention is the production. of a reinforced concrete pipe wherein the end portions are provided with caps so constructed as to form at one end a socket and at theopposite end a neck, .so that two sections of a pipe may be easily interlocked for constituting'a tight Joint, and at the same time the caps will prevent wear upon the body portions of the pipe.

A still further object of this invention is the production of a reinforced concrete pipe wherein the end portions are slanted or bev eled so'that a pipe may either extend in a straight line or should the ditch in which the same is placed be curved the pipe may be turned so as to conform in shape to the ditch.

With these and other objects in view this invention consists of certain novel. combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing:

Figure 1 is a top plan view of the reinforced concrete pipe as .constructed in accordance with this invention, portions of the same being broken away.

Fig. 2 is a longitudinal section through vthe concrete pipe.

Fig. 3 is an end view of the pipe, illustrating the neck formed thereon.

Fig. 4 is a section taken on the line 4-4 of Fig. l.

Fig. 5 is an end elevation of the mold for the pipe.

ferring to the accompanying drawings by numerals it will be seen that the reinforced concrete pipe preferably is cylindrical in shape to constitute a body 1. This body 1 is provided with an enlarged longitudinally extending bore 2, extending through its central portions as shown in Fig. 2. When this body 1 is being constructed a plurality of longitudinally extending slanting reinforcing rods Bare used, which are positioned within the concrete bodv 1 in parallel relations to each other,

vas shown clearly in Fig. 1. -lfn order to retain these rods in their correct positions within the body 1 while the cement is yet green, a plurality of tie strands 4 are used, these strands being provided with av number .of eyes 5 through which the rods 3 extend.

These tie strands 4 are carried at spaced intervals throughout the entire length of the body 1, and, therefore, it will be seen that the body 1 will be efficiently reinforced after the concrete becomes hardened.

Both ends of the concrete body 1 are slanted in the same general direction, as disclosed clearly in Figs. 1 and 2, one end of the body being provided with the neck 6. This neck 6 is slightly smaller than the outer circumference of the body 1, and has positioned thereon the metallic cap 7. This cap 7 fits upon the neck and also over the slanting end 8 of the neck. To correspond with the slanting end 8 of the neck 7 there is provided an annular slanting abutment shoulder 9 extending to the annular socket 10. The cap 7 has a wall 11 fitting upon the shoulder 9 which communicates with the integral annular Harige 19. fitting upon and within the socket 10. The forward portion of the cap 7 which fits upon the'slanting portion 8 of the neck 6 is provided with a plurality of openings 13 which communicate with the pockets 14 in which the ends of the rods 3 are adapted to extend. The nuts 15 are carried upon these threaded ends and, therefore, will fit within the sockets so as to retain the rods 3 against longitudinal displacement, and at the same time will be positioned out of the way when two sections of pipe or more are being connected. The opposite end of the body 1 is provided with an enlarged socket portion 16 and with a reduced channel 17 formed adjacent thereto. A metallic reinforcing cap 18 is positioned so as to fit within the socket 16, and it will be noted that this socket slants as does this end of the body 1. The cap is provided with an overhanging U-shaped portion 19 tting around the end of the body 1, so as to rest within the channel 17 for extending in the same plane, as the outer surface of the body l. The inner portionfof the cap 18 is provided with' openings 13' communicating with the pockets 14 in which the nuts 15',`

are carried. .It willbe noted that the section as herein disclosed has each end slanting or beveled in the same direction, while one end is provided with a neck, and the other end is provided with a socket. There fore, when a number of sections are used for constructing a continuous conduit, -a neck 6 may be passed.v into a socket 16 thereby form ing a tight closure so as to allow the bores of the bodies to communicate with each other for forming a continuous passage. As long as the ditch or other element in which the pipe is positioned extends in a straight line theseveralsec'tions of the pipe may be positioned so as to allow their beveled or slanting ends to extend in the same general direction that the same are connected. When,

however, there is a turn or curve in the ditch one section of the pipe may be turned so as allow its slanting or beveled portion to extend in the-,opposite directionto the next adjoining sections of the pipe, and, therefore, when the neck thereof is positioned crete. Furthermore, the construction of the neck and sockets of the pipes will allow the ipes to be easily connected to form a tight ]ontwhile the pockets formed in the end portions of the body will allow the retain- .ing nuts to be carried therein without interfering with the neck of the pipes.

By referring to Fig. 5 it will be seen that a very eiicient mold has been produced which comprises a plurality of -sections 20. Each section is bent backwardly upon itself to provide a U-shaped coupling 21 which is adapted to carry the iat end or side edge 22 of the ends adjacent the sections 20. This mold is adapted to be positioned upon the outer portions of the pipe when the same is being formed for retaining the same in its .correct position when the concrete is yet green, while an ordinary core maybe carried within the body 1 to form`\the bore 2. These couplings 21 may be of spring-like construction so as to bind upon the straight portions 22 of the ends adjacent the sections 20, whereby the mold will be prevented from accidentally falling apart when in use.l

After the body 1 has become hardened, however, the sections may be easily pulled apart so as to be removed from engagement with the body 1.

What is claimed is: In a device of the class described, the combination ofan elongated body having -a central' bore extending therethrough, a reduced y neck formed upon one end of said body, thereby forming an abutment shoulder, a cap positioned upon said neck, said cap overhanging the end of said neck, a wall-formed i upon said cap and bearing uponsaid shoulder, a flange extending from said wall and fitting uponl said body, whereby said neck and body will-be reinforced, and the overhanging portion of said cap having openings formed therein, whereby vpartial access may be had to the end of said neck.

In testimony whereof wehere'unto afiix our signatures. r
